ATENT MACHINE FOR GATHERRNG POTATO-BUGS.

SPECIFICATION forming part of Letters Patent No. 309,955, dated December 30, 1884.

Applicati n filed May 14, 1884. (N0 model.)

To (LU, whom, it may concern.-

Be it known that I, PEHR Jonas JACOB- soN, of South Manchester, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Machines for Gathering Potato-Bugs; and I do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts.

Figure 1 is-a top view of my machine. Fig. 2 is a view in longitudinal vertical section of the machine, looking toward the pan, and on a plane passing through the axis of the revolving brush-frame. Fig. 3 is a vicwin vertical crosssection of the device, looking toward the rear, on a plane passing through the revolving bruslrframe near the center of its length.

The object of my invention is to furnish an improved machine for removing potatobugs from vines standing in the field, and to make into a box as the machine is drawn across the field, from which box the bu gs may be removed and destroyed.

It consists in the combination of devices for operating the brushes,f0r cleaning the brushes, and for adjusting them to various heights, as more particularly hereinafter described.

In the accompanying drawings, the letter a denotes a frame of any suitable 1nateria l-as woodmou nted upon wheels Z 1/, near the rear partof the frame, and having a smaller wheel, 0, near the front part, which, arranged like a colter, serves as a guide; (1, an upper frame pivotally connected to the lower frame by bars 0, forming a parallel-motion device that allows the upper frame to be raised orlowered at will, as by means of a lever, f, pivoted to the lower frame, and having acam-arm located between the upper and lower frame in such manner that the rotation of the cam by means of the lever lifts or lowers the upper frame. A cog-wheel, g, is secured to the hub of one of the wheels I), and turns with the wheel. J ournaled in bearings in the upper frame, d,

the sleeve Z, that is rotarily arranged in a bearing in the cross-bar d, and the beveled cog 1, fast to the rear end of this sleeve, is in mesh with a beveled cog, m, secured on the rotary shaft m, that is driven by the cogwheel h", fast to the shaft 71 and in mesh with a cog-wheel, on fast to shaft m. Cog-wheel Z is secured to the forward end of the sleeve 1,

and is in mesh with and turns the cog-wheel k", fast to one end of the rotary brush-holder k. The outer ends of each pair of arms of the brushframe bear one of these rotary brushholders, to which is fastened a cog-wheel,also in mesh with the cog 1*. (All but one of the wheels 011 the brush-holders have been omitted from the drawings to avoid confusion.) The rotary holders are slitted lengthwise, and the brushes a are clamped in the slit in the holder, as by means of screws. The rotation of the wheel I) by means of the connected mechanism described causes the brush-frame to turn upon its axis and the holders to rotate in their bearings in the frame in such manner that the brushes in succession sweep the bugs from the vines into the box 0. The rotation of the brushes prevents the bugs from being thrown off by the repeated turning of the frame, and also enables the fixed brush a, that projects inward from the upper edge of the box, to clear the brushes on the frame. The box 0 is fastened to the frame and is open upon the side toward the brushframe, as shown. The seat 1) is attached to the frame by bolts in the ordinary manner.

I claim as my invention- 1. In combination,awheeled frame, a, bearing the receiving-pan 0, andarevolvingbrushframe, 7;,which bears aseries of rotary brushes, a, driven by gears in mesh with a central gear, Z", driven by the rotation of the main wheel of the vehicle by means of intermediate mechanism, all substantially as described.

2. In combinatioma Wheel-supported frame, verticallyadjustable frame bearing a series IO a, bearing a box, 0, a brush, n, fixed to the of rotary and revolving brushes, and a brush frame and projectingover the box,andarevo1vfixed to the lower frame, whereby the moving ing brush-frame,k, bearingthe rotary brushes brushes are cleaned, all substantially as de 5 n, fixed in the brush-holders is, all substanscribed, and for the purpose set forth.

tially as described, and for the purpose set PEHR J OHAN .TACOBSON. fo rth. WVitn esses:
